Patients taking nuclear meds can set off radiation detectors.CHICAGO -- Patients given radiopharmaceuticals for diagnostic or therapeutic nuclear medicine procedures can trigger radiation detectors up to 3 months after the procedure, Lionel S. Zuckier, M.D., said at the annual meeting of the Radiological Society of North America The Radiological Society of North America (RSNA), founded in 1915, has the purpose to "promote and develop the highest standards of radiology and related sciences through education and research". .
These patients should be given appropriate documentation, said Dr. Zuckier, director of nuclear medicine and positron emission tomography positron emission tomography: see PET scan.

"Many patients have been picked up and detained ... and now we expect it to be a more common occurrence with the increasing number of extremely sensitive portable radiation detectors being distributed to local, state, and federal emergency responders," he said.
Physicians should counsel patients about informed consent and advise them to carry letters of clarification to make any interactions with law enforcement personnel easier, he said.
This is consistent with guidelines issued by the Society of Nuclear Medicine and the U.S. Nuclear Regulatory Commission Nuclear Regulatory Commission (NRC), an independent U.S. government commission, created by the Energy Reorganization Act of 1974 and charged with licensing and regulating civilian use of nuclear energy to protect the public and the environment. . "This letter should include a contact name and number so that the information can be verified at any time. Our department has a 24-hour number that can be called," said Dr. Zuckier, also a professor of radiology at the University of Medicine and Dentistry of New Jersey The University of Medicine and Dentistry of New Jersey is the state-run health sciences institution of New Jersey and comprises eight distinct academic units: the New Jersey Medical School, the New Jersey Dental School, the Graduate School of Biomedical Sciences, the School of , Newark.
According to Dr. Zuckier, there were 18 million nuclear medicine procedures performed in 2002 in the United States. With 10,000 portable Homeland Security radiation detectors in use, there is great potential for patients to be inconvenienced at airports or other security points.
His study, which he presented at the meeting, examined the strength of five radiation detection devices currently in use by Homeland Security.
Therapeutic radiopharmaceuticals, such as iodine, used in treating thyroid disorders, can be detected in the body and therefore have the potential to trigger radiation detectors up to 3 months after the procedure. Patients who undergo cardiac exams with thallium thallium (thăl`ēəm), metallic chemical element; symbol Tl; at. no. 81; at. wt. 204.383; m.p. 303.5°C;; b.p. about 1,457°C;; sp. gr. 11.85 at 20°C;; valence +1 or +3. can trigger alarms for up to 30 days, and patients who undergo bone and thyroid scans have detectable radiation levels for up to 3 days.
